Fallout 3

You can get this Quest by talking to Lucy West in Megaton, Even King in Arefu or by reading about the "Arefu Incident" on one of the Family's terminals in the Meresti Metro Station but for the purposes of this guide we are going with the Lucy option, because you will most likely bump into her during the "Following in His Footsteps" Quest anyway. When talking to Lucy she will ask you to deliver a letter to her brother Ian in Arefu.

When you arrive at Arefu, Evan King (the town sheriff/mayor) will take a pot-shot at you. After explaining who you are and what you're doing there you will get the chance to ask why Even is so jumpy, to which he'll explain about the "Family" and ask you to check on the citizens of the town. The first two families who visit will be ok if a little nervous but the third family will be dead with suspicious marks on their necks.

Before or after you go to the West residence, you can pick the lock on Evan's house (if your lockpicking level is high enough) and grab the Bobblehead from his desk.

After you have finished examining the West Residence, return to Evan and tell him the bad news. After informing him of what has happened, Evan will ask about Ian to which you will reply that he wasn’t there. To get a rough idea of where to look, ask Even if he has any idea where The Family might be and he'll place 3 Map Markers on your map showing the locations of Northwest Seneca Station, Hamilton's Hideaway and the Moonbeam Outdoor Cinema but if your Medicine Skill is at 90 or higher when examining the corpses of the West Family, Evan will reveal the location of the Meresti Trainyard. The Meresti Trainyard is the correct location so make your way there but watch out for Raiders and Mirelurks on the way there and Mirelurks and traps galore inside the actual tunnels. When you're almost at the spot in the Tunnels where The Family is hiding, you'll be stopped by Robert who will tell you to go away but will let you in if you either produce Lucy's letter or bribe/sweet talk him if your Speech level is high enough.

When you get into Meresti Station, there are 3 ways to learn where Ian is being kept:

1: Talk to Karl the shopkeeper and either use the Black Widow option (if playing as a girl) or pass the Strength Challenge (if your Strength S.P.E.C.I.A.L is high enough). Pass this and he'll give you the access codes to the terminal next to his room so you can let yourself in.

2: Talk to Vance then learn about the "Family" when he says that you're not ready for his teachings (or words to that effect), he will also give you access to the Family's terminals on the Platform.

3: Pass a Speech Challenge when talking to Justin who will also give you the access codes to the terminal next to his room so you can let yourself in.

For the purposes of this Guide we will be going with option 3 since it's the fastest way. Vance won't be happy but will respect whatever Ian decides.

Once you've got access to Ian's room, go there and get him to explain what happened to his family after which you’ll have to decide what to do about him as you'll have 2 options:

1. Leave him with The Family.
2. Persuade him to return to Arefu.

Whichever one you choose you will have to relay that decision to Vance then to Evan King back in Arefu, the trophy will pop soon afterwards.

Whilst you're talking to Vance, you can also persuade him to leave Arefu alone and/or Protect it in return for receiving Blood Packs from Arefu. If you go down this route, you will need to return to Vance after informing Evan of Ian's decision.

Note: After finishing this Quest you can speak to Vance about becoming a vampire, do this and you'll earn a new Perk called "Hematophage" which allows you regain 20 points of health from each Bloodpack you drink.
